Close to the spherical cap, so as not to reduce the space for the insertion of the finger, a, cutter disk 9 is arranged, which may have any desired shape but preferably is a circular disk of a diameter smaller than the smallest diameter of the conical portion arranged near the line of intersection between the conical portion 'I of the thimble and the cap 8. The cutting disk is therefore confined to and contained within the inner contour of a normal conical thimble body, but is arranged close to the Walls of the thimble so that by virtue of its position nea the cap portion it cannot be reached acciden, ally by the finger inserted into the thimble and even if reached offers no opportunity for cutting, on account of its close fitting into the conical and spherical portion.

The disk 9 is arranged transversely with respect to the longitudinal axis of the thimble and it is mounted on a central embossment I or hub portion projecting centrally from the cap 8 and carrying a pin or bolt II, which may either be riveted to the cap 8 as shown at I2 in Figures 3 and 5, or may be provided with a small screw I3, which permits removal of the cutter disk or a change of disks.

The thimble, in order .to make the disk accessible is provided with an opening, cut or slot I4 which may have any desired shape: circular, elliptical, rectangular or the like, but which preferably has the shape of a longitudinal slot of such Width that a thread may be easily passed through it while it is sufficiently narrow to prevent objects or parts of the human body to penetrate into the interior of the thimble, thereby protecting against accidental damage by the cutting edge of the cutter disk.

The latter may be a thin circular disk of steel, with a ground edge, similar to a razor blade which is preferably rotatably mounted on the hub portions of the cap.

Although the operative portion of the cutter disk is small, a circular cutting edge has the advantage of being able to change said operative portion at intervals in a very simple manner, thus keeping permanently a finely ground -cutting edge in the operative position.

A small protuberance or stud I5 arranged on the disk permits rotation of the same if required.

To cut a thread (usually inserted into a needle) it is only necessary to pass the thread through slot It from the outside to the inside or if the end of the thread should be short, to move the thimble close to the spot where the cut has to be made and .to pull the thread in such a direction that the cutting edge will be pressed against he thread. 1i Where ,cuts are not to be made close to the surface, insertion of the thread from either side may take place.

The cutter disk 9 is moved from time to time in order to make fresh portions of the cutting edge face the slot.

In the modification shown in Figure 5 the arrangement is substantially the same as that described, the fixation of the thimble on the container being however performed by means of a protruding annular ledge II on the container entering into a groove provided in the interior of the thimble.

According to the modification shown in Figures 9 to 11, the cutter disk is not fixed by means of a `central pin but is merely held near the intersection between the conical portion 1 and the spherical cap 8 of the thimble or on an em- -bossment similar to that shown in Figures 3, 5, 6 and 8 by means of a spring I9 which may be inserted into grooves 20 provided in the interior of the thimble. The spring is of a suitable shape, for instance, it is circular or of U, V or W-shape, with parts protruding into the interior of the thimble and, when inserted and held within the groove by virtue of its elasticity, it Will hold the cutter disk in close proximity to the cap. The 4cutter disk is thus confined to the space left between the spring 20 and the cap 8 and is held firmly but rotatably in this space. It may be rotated by means of the protuberance or stud I5 as shown in Figures 8 and 11 or by means of a small hole 2l provided on the disc.

It will be clear from the above that the invention may be used in connection with thimbles, whether or not attached to a kit or outfit. However, it will be understood that the fact that the smooth outline of the outfit is in no way impaired is a notable advantage. A further advantage resides in the fact that the operativeness of the thimble itself is not affected as is the case where cutting edges or the like are provided either on the edges of the cap or on the outside in general.

It is, however, clear that a number of changes may be made without departing from the scope of the invention and it is, therefore, emphasized that the foregoing specification is illustrative and is not intended to limit the scope of the invention as claimed.

Having described the invention, what is claimed as new is:

A thread cutter for thimbles, the latter having a body consisting of a single piece with a conical portion and a spherical segment forming its cap portion, and a flat circular disk of a diameter smaller than the smallest diameter of the conical body portion, having a circumferential cutting edge contained completely within the hollow interior of Ithe thimble body, at the intersection between the conical and the spherical portion, the circumferential portion of said disk resting on and held by the said cap portion on one side, the conical portion of the thimble being provided near its small end with a groove located lbelow the cutter disk, a spring seated within said groove, said spring holding said cutter disk rotatably, pressed against the cap portion, the thimble body being provided with a single narrow slot extending longitudinally of the wall of the thimble body and across said disk for making the cutting edge of the disk accessible from without.
